Zusammenfassung:Systems that detect a positional relationship between an informal processing device and an external keyboard are disclosed. A system includes an external keyboard including a first communication unit, an incoming coil disposed inside thereof, and an input controller configured to control the first communication unit to transmit operating information indicating an input operation from a user, information processing device including a second communication unit configured to communicate with the first communication unit, a planar portion on which the keyboard is mountable, and a feeding coil disposed below the planar portion, the feeding coil configured to supply electricity to the incoming coil by an electromagnetically induced coupling, and a position detector configured to detect a positional relationship between the planar portion and the keyboard based on a coupling strength of the electromagnetically induced coupling between the feeding coil and the incoming coil. Similar apparatus and methods are also provided.
